First off, does it show any codes? Secondly, try the IAC, this located on the throttle body. Clean it or replace it if needed, if that's the prob, it should clear alot of the troubles up.

Also check and see if the notorious splice is bad.

I replaced the IAC wit no difference n to my knowledge there r no codes no check engine light

Not all codes will trip the Check Engine Light. There is an easy way to check them. Check the FAQ in this section for a how to and a list of the codes. Also did you check to see if your getting correct fuel pressure? Did you change the fuel pressure regulator?
